The following section describes the relationship between Power Spectral Density (PSD) and Equivalent Isotropically Radiated Power (EIRP), and the channel width.
EIRP = PSD + 10 log (channel width)
For example, with a PSD of 5 dBm/MHz and a channel width of 20MHz, the EIRP is:
320MHz channel width is not supported for Wi-Fi 6E devices and is added in the following diagrams for illustration purposes only. 320MHz channels will be added in Wi-Fi 7.
